Respiratory System Questions and Answers with verified solutions

Respiratory System Questions and Answers with verified solutions allergic rhinitis - ANS- allergic reactions occuring within the nasal chambers are given this general name alveolar sac - ANS- during lung gas exchange, carbon dioxide molecules move toward the alveoli - ANS- the smallest branches of the respiratory system tubes terminate in clusters of microscopic air sacs; fill with oxygen; capillaries that surround the alveoli allow the exchange of CO2 and oxygen alveoli sacs - ANS- tiny air sacs in the lungs that are involved in the exchange of gases that takes place in between the blood and the atmosphere asthma - ANS- defined by increased constriction of the trachea and bronchi in response to various stimuli, narrowing the air passageways and decreasing ventilation efficiency, can be reverse in time, or with therapy bicarbonate ions - ANS- approximately 70-75 percent of carbon dioxide is transported in the blood in the form of bronchi - ANS- the two primary tubes that branch from the trachea; split up much like tree branches; air flows through these tubes, then into the bronchiole; get smaller until they reach the alveoli bronchial tubes - ANS- the trachea branches into these structures bronchioles - ANS- there is no cartilage in the tubes when the bronchi become these bronchitis - ANS- the common name for inflammation of the bronchial tree carbon dioxide - ANS- the respiratory centers in the brain are regulated indirectly by the bloodstream's level of carboxyhemoglobin molecules - ANS- approximately 25-30 percent of the carbon dioxide in the body is carried as cartilage - ANS- the trachea is supported by a series of C-shaped of this; form the anterior and lateral sides of trachea, which protects and maintains air passage cilia - ANS- tiny hair-like structures that aid in keeping the air passages clean circulatory system - ANS- oxygen and carbon dioxide are transported between the cells of the body and the respiratory system by the coughing - ANS- defense mechanism that expels mucus build and foreign substances cricoid cartilage - ANS- the cartilage of the larynx that resenles a signet ring and connects the trachea and larynx diaphragm - ANS- concave dome shaped muscle; the major muscle involved with the process of breathing diffusion - ANS- the driving forcce behind the exchange of gases in the alveoli is the process of; passive process diphtheria - ANS- caused by bacterium, a grey membrane forms in the throat blocking the air way completely; vaccine is part of normal immunization dyspnea - ANS- difficult or labored breathing is referred to as emphysema - ANS- a very serious disease of the lungs in which the lungs lose their elasticity eustachian tubes - ANS- the lateral walls of the nasopharynx contain openings of tubes fromthe middle ear known as external intercostal muscles - ANS- during inspiration, the ribs are raised upward and outward by a set of respiratory muscles called external nares - ANS- the nasal cavities open to the external environment at the nostrils, also known as fungal diseases - ANS- fungal spores enter the respiratory system attached to dust particles; spores in the dust causes usually minor infections, but in severe cases it can spread to other parts of the body glottis - ANS- the opening to the larynx referred to as hard palate - ANS- located at the base of the cavity, separating the oral and nasal cavity; when masticating it allows breath through the nasal cavity hemoglobin molecules - ANS- the great majority of oxygen is carried in the body in association with hydrogen ions - ANS- the respiratory center is activated by the cerebrospinal fluid level of in front of - ANS- the trachea is located...the esophagus innate immunity - ANS- gives some protection against microorganisms via blocking their way into the body, and by removing them from respiratory surfaces involuntary - ANS- while the contraction of skeletal muscles is usually voluntary, the control of breathing is larynx - ANS- the strucutre that produces the sound of the voice as air passes through it; contains thyroid cartilage (adam's apple) lobes - ANS- the left lung has two and the right lung has three low pressure - ANS- the underlying principle of breathing is that air flows from the region of high pressure to a region of lower respiratory - ANS- trachea, primary bronchi, lungs lungs - ANS- vibrations of the vocal chords are due to air exhaled from; the relaxtion of respiratory muscles compresses the thorax and increases the air pressure mouth and nose - ANS- the portal entry and exit for air that is a part of the respiratory system nasal cavity - ANS- Nasal septum divides the nasal cavity into left and right sides; mucus forms to trap debris in the air; blood and mucus humidify and warm the air coming through nasal conchi - ANS- passageways in the nasal cavity are separated from one another by body extensions of the nasal septum known as olfactory region - ANS- sensation occurs when airborne molecules are moved into the nasal cavity; at the roof of the nasal cavities the sense of smell is associted with an area called oropharynx - ANS- the digestive and respiratory passageways meet one another at a region of the pharynx referred to as what parietal pleura - ANS- the outer layer of pleura lining the inner surface of the thoracic cavity passive process - ANS- while inspiration is an active process, the process of expiration is a pharnygeal tonsils - ANS- the mass of lymphatic tissue on the medial posterior wall of the nasopharnyx pharnyx - ANS- the mouth and nasal cavities meet in this region; passageway for both respiratory and digestive system; leads air from the nasal cavity to the larynx; contains the tonsils which aids in defense against infection pitch - ANS- because men have longer vocal chords, their voices have a lower pleura - ANS- the two-layer membrane surrounding each lung pneumonia - ANS- infections of the lungs, most is bacterial, but some are viral, phlegm is likely to fill parts of the lungs pneumotaxic area - ANS- the rate of breathing is controlled by an area of the brain known as pons - ANS- breathing is controlled by an area of the brain called the respiratory control center, which includes part of the medulla oblongata and this pulmonary - ANS- a term used in association with the lungs pulmonary artery - ANS- blood enters the lungfrom the heart through this major artery red blood cells - ANS- during lung gas exchange, oxygen molecules move toward the respiration - ANS- breathing, gas exchange between the lungs and the blood, transport of oxygen and CO2 in blood, as well as gas exchange between blood and tissues respiratory muscles - ANS- pressure changes occurring in the lungs can be traced to the activity of skeletal muscles known as resting tidal volume - ANS- th
